Christians: What do you think of St. Cyril of Alexandria?

I am an atheist and I respect Carl Sagan. Cyril DIDN'T kill her, a mob did! There is no indication that Cyril ordered the "hit". He may not have liked her and he may have spoken against her but that doesn't make him responsible for the actions of a mob. Mobs of people do terrible things all the time. Because they are a mob, it is difficult to determine who is at fault. So the most common thing to do is blame the person or the idea that the mob represents. It's convenient, easy to understand and WRONG. Each individual in the mob is responsible for their actions in any mob violence. It may be extremely difficult to determine but that doesn't make it less true.
